Dead Trigger. Here's a game that began as something cool, then blossomed into one of the finest shooters for iOS and Android. Developer Madfinger Games has been generous with each update, and it appears the newest is no exception. Available just in time for Halloween, this downloadable content adds zombies with jack o' lanterns for heads, along with a creepy Haunted Graveyard stage.

There's more, of course. Players will take advantage of the new crossbow, and can purchase the mini gun at a discount price. We've also heard of something called the Alien Gun effect, but don't know what it does yet.

This Halloween Dead Trigger update is currently available for Android, and Madfinger submitted it to Apple for approval, so we expect to see it on iOS any day now. If you've been thinking about downloading this game, now's the time. Ah yes, and check out the trailer below.
